HERMAN MILLER, OF NEXV YORK, N. Y.

vCLOSING KEROSENE AND OTHER CANS.

SPECIFICATION forming part of Letters Patent No. 312,372, dated February 1'7, 1885.

Application filed February 13, 1884. (No mod cl.)

T0 aZZ whom/it may concern.-

Be it known that I, HERMAN MILLER, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Devices for Closing Kerosene and other Cans, of which the following is a specification.

My invention is applicable more particularly to tin cans, such as are largely employed for crude petroleum and for kerosene, and which commonly contain five gallons or less; but the invention may be embodied in sheetmetal cans for containing other liquids and substances.

The invention relates to cans in which the can top or head has soldered to it around the fillinghole a ring which is internally screwthreaded, and which is closed after the can is filled by an externally-threaded plug, the internal and external threads of the ring and plug being tapered, so that provision is afforded for always tightly closing the can by screwing the plug in until it comes to a tight fit in the ring.

The invention consists in the combination, with a can top or head, of a ring having a taper screw-threaded interior, and also having a downwardly-flaring flange extending from its upper part, and soldered to the can top or head, and a stopper or plug having a taper screw-threaded exterior fitting the ring.

The invention also consists in the combination, with a can top or head having a fillinghole, of a ring soldered thereto around said hole, and having a taper screw-threaded interior, and a cup-shaped stopper or plug having a taper screw-threaded exterior destitute of a shoulder, and provided with lugs or cars with which a wrench may be engaged for turningthe stopper or plug.-

111 the accompanying drawings, Figure 1 is a plan of a can-top closed by my improved devices. Fig. 2is a section on the dottedline a: m, Fig. 1. Fig. 3 is a sectional view of the stopper or plug detached. Fig. 4 is a sectional view of the screw-threaded ring detached. Fig. 5 is a sectional view of the portion of the cantop immediately surrounding the filling-hole; and Fig. 6 represents a wrench which may be employed to insert or remove the stopper or plug.

Similar letters of reference designate corresponding parts in all the figures.

A designates the can top or head, in which is the usual filling-hole, a.

B designates a ring, which is soldered to the can-top around the hole a, and which receives within it a stopper or plug, 0.

As here shown, the can-top A is formed with aslight groove or annular depression, b,around the hole a, and the ring B has a flaring flange, c, projecting downward and outward from its upper part, and fitting or resting in said groove or depression 12, as best shown in Fig. 2. The ring B may be formed of zinc or other suitable metal or alloy, and its construction with the flange 0 gives it great strength. The edge of the flange c is secured in the groove or depression b by solder, and thus the ring B is soldered to the can-top around the filling-hole a. This is done before the can is filled. The interior of the ring B tapers from its top clownward, and the interior has formed in it a female screw-thread, which preferably extends throughout the depth of the ring. The stopper or plug 0 is here shown as cup-shaped, and it may be struck up from zinc or other sheet or plate metal by a suitable die. It has a taper exterior, and is destitute of a shoulder. It has formed upon its exterior a male screwthread fitting the screw-threaded interior of the ring, and, as here shown, the screw-thread extends throughout the depth of the plug. At the upper edge the stopper or plug 0 is provided with diametrically-opposite lugs or ears (I, and D, Fig. 6, designates a wrench in which are slots 6 e, that are capable of being engaged with the said lugs or ears to turn the stopper or plug in screwing it in or out.

The stopper or plug may be made of cast metal, if desired. 1

Inasmuch as the plug 0 and ring B are both taper, and the plug is destitute of a shoulder on its exterior, the plug may be screwed in until it will make a tight fit in the ring, and if a little red lead or other suitable material be applied to the thread the can will be hermetically closed.

When it is desired to open the can, it is necessary only to unscrew the plug, and the can may be used as many times as desired.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with the can top or head A, of the ring B, having a taper screw-threaded interior, and also having the downwardlyflaring flange 0, extending from its upper part, and soldered to the can top or head, and a stopper or plug having a taper screw-threaded exterior, substantially as herein described.

2. The combination, with the can-top or canhead A, having the hole a, of a ring soldered thereto around said hole, and having a taper 15 screw-threaded interior, and the cup-shaped stopper or plug 0, having a taper screw-thread ed exterior destitute of a shoulder, and provided with the lugs or ears d, to which a wrench may be applied, substantially as herein de- 20 scribed.

HERMAN MILLER.
